SPECIFICATION forming part of Letters Patent No. 769,404, datedSeptember 6, 1904.

Application filed June 15,1904. Serial No. 212,682. No model.)

"/1 (LIZ 11-71mm it 71mg; concern:

Be it known that I, J OHN LPOTTIJR, a citizen of the United States,residing at Florien, Sabine parish, and State of Louisiana, haveinvented certain new and useful Improvements in \Vire- Stretcher-s; andI do declare the following to be a full, clear, and exactdescription ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to new and useful improvements inwire-stretchers; and the object of the invention is to produce a simpleand efficient mechanical appliance for gripping and securely holding thewire while being stretched.

More specifically, the invention comprises a wire-stretching deviceconsisting of a handle with a fixed jaw and carrying a pivotal jaw,which is actuated by means of a rotatable shaft having a hand-wheelthereon.

The invention consists, further, in various details of construction andin arrangements of parts which will be hereinafter more fully describedand then specifically defined in the appended claim.

The invention is illustrated in the accompanying drawings, which, withthe letters of reference marked thereon, form a part of thisapplication, and in which Figure 1 is a side elevation of my improvedwire-stretching apparatus. Fig. 2 is an enlarged detailed view showingthe manner of actuating the pivotal jaw. Fig. 3 is an edge elevation ofthe device.

Reference now being had to the details of construction by letter, Adesignates a shaft, which may be of any size or shape, and B designatesa fixed jaw secured to one face of said shaft and preferably at the endthereof.

One face of said jaw is roughened, as at B, in order to securefrictional contact with the pivotal angle-lever, the free end of whichforms a jaw (J. Said angle-lever is pivotally mounted upon a pin .D,carried by said shaft. Said jaw O is roughened and is adapted tocooperate with the roughened surface of the jaw B to securely hold thewire E between said jaws.

Mounted to have a rotary movement in bearings F, formed in the collarsor rings F, is a rod K, one end of which has a hand-wheel K fixedthereto, while the other end is pivoted to the curved end of jaw O, anda portion of said rod is threaded and engages threaded apertures in thestationary collar, whereby the rod is rotated in one direction or theother said jaw C may be thrown toward or away from the fixed jaw B.

In operation a wire to be stretched is inserted between the two jaws,and by turning the hand-wheel K. the pivotal jaw may be thrown incontact with the wire, causing the latter to be securely gripped betweenthe jaws, after which the lever may be fulcrumed over any object and thewire stretched to the extent desired, after which the device may bedetached from the wire by rotating rod in the opposite direction, thuscausing the pivotal jaw to be thrown from contact with the wire.

\Vhile l have shown a particular detailed construction of the deviceillustrating the features of my invention. it will be understood that Imay vary the details of the device, if desired, without in any waydeparting from the spirit of the invention.

Having thus described my invention, what I claim to be new, and desireto secure by Letters Patent, is

A wire-stretcher comprising a shaft with a fixed jaw thereon, a pivotaljaw carried by said shaft, a rotatable rod, hearings in which said rodis journaled, a pin carried by said rod and having a play in anelongated slot in the curved end of said pivotal jaw, a handwhecl fixedto the end of said rod and adapted to turn in a cut-away portion of saidshaft, whereby the end of said pivotal jaw may be thrown toward or awayfrom the fixed jaw, as set forth.

In testimony whereof I hereunto atlix my signature in presence of twowitnesses.

JOHN \V. POTTER.
